Overview of the Thermalright Assassin X 120R SE Plus CPU Cooler
The Thermalright Assassin X 120R SE Plus CPU Cooler offers a balance of affordability and efficiency, priced at C$25.59. This cooler is designed with a robust cooling system featuring four 6mm heat pipes, which enhance heat transfer and dissipate heat effectively. Thermalright, a brand with over 20 years of experience in the computer accessories market, has engineered this cooler to support a range of CPU sockets, making it versatile for various builds. The combination of double PWM fans allows for an airflow of up to 66.17 CFM while maintaining a noise level of less than 25.6 dB(A), creating a quiet and efficient cooling environment.
Overview of the Gamma A40 ARGB BK CPU Cooler
The Gamma A40 ARGB BK CPU Cooler, priced at C$29.09, presents a compact design that measures 133mm in height, ensuring compatibility with most computer cases. This cooler is capable of handling up to 200W TDP, making it suitable for high-performance applications. Equipped with a 100mm fan, the Gamma A40 promises better performance compared to other compact coolers in its class. Additionally, its direct-touch heatpipe design with four 6mm heat pipes increases the contact area for effective cooling, making it a strong contender for those who seek efficiency in tight spaces.
Cooling Performance Comparison
When comparing cooling performance, the Thermalright Assassin X 120R SE Plus offers a maximum airflow of 66.17 CFM, which is notable for its price range. In contrast, the Gamma A40 is rated for a thermal design power (TDP) of up to 200W, suggesting it can handle more heat than the Assassin X under high load situations. The unique direct-touch heatpipe design of the Gamma A40 enhances its cooling capability by maximizing contact with the CPU, while the Assassin X utilises its four heat pipes and dual PWM fans to deliver consistent cooling performance at a lower noise level.
Noise Level and Acoustic Performance
Noise level is a critical factor for many users, and the Thermalright Assassin X 120R SE Plus excels in this regard, operating at a maximum noise level of 25.6 dB(A). This is relatively quiet and ideal for users who prioritise a silent computing environment. While the Gamma A40 does not specify its noise levels, the performance of its 100mm fan is designed to provide effective cooling while maintaining reasonable noise output. Without specific data, it’s difficult to quantify how it compares to the Assassin X, but users should consider the importance of noise levels in their decision-making process.
Design and Aesthetics
The design of the Thermalright Assassin X 120R SE Plus is practical, focusing on performance with its straightforward layout and dual fans. In contrast, the Gamma A40 features a brand-new top cover with classic round dot matrix elements, adding a modern aesthetic appeal to any build. The compact height of the Gamma A40 also contributes to its attractive design, making it a suitable choice for smaller cases where space is a premium. Users looking for visual appeal alongside performance may lean towards the Gamma A40's more contemporary look.
Installation and Compatibility
Both coolers are designed for easy installation and compatibility with various mainstream platforms. The Thermalright Assassin X 120R SE Plus supports multiple Intel sockets (including 1150, 1151, 1155, 1156, 1200, 1700) and AMD sockets (AM4, AM5), providing flexibility for different builds. Similarly, the Gamma A40 claims easy installation on Intel and AMD platforms, although specific socket compatibility details are less comprehensive. For users who frequently upgrade or change their CPUs, the wide compatibility offered by the Assassin X may be a decisive factor.
Brand Reputation and Reliability
Thermalright has established a solid reputation over the past two decades, focusing on the research and development of computer accessories. The brand's experience in the market translates into reliable and well-engineered products, such as the Assassin X. On the other hand, the Gamma A40 is produced by Ocypus, a less well-known brand, which may raise questions about long-term reliability and customer support. Users might prefer the proven track record of Thermalright when considering the longevity and support of their cooling solution.
Which should you buy?
Ultimately, the choice between the Thermalright Assassin X 120R SE Plus and the Gamma A40 ARGB BK CPU Cooler depends on your specific needs and preferences. If you prioritize quiet operation and a proven brand reputation, the Thermalright Assassin X is a compelling option at C$25.59. However, if you need a compact cooler with strong cooling performance capable of handling higher TDPs and a modern aesthetic, the Gamma A40 at C$29.09 could be the better choice. Both coolers have their strengths, so assessing your build requirements will lead you to the right decision.
